Smart Grid

Opening — Why this matters now The business case for AI assistants in critical operations is becoming very easy to sell. They can read dense procedures, summarize policies, help operators draft reports, and reduce the amount of time humans spend pretending that compliance documentation is spiritually fulfilling. That is the good version. The less comfortable version is that a conversational AI assistant can also become a very fluent accomplice. Not because it has malicious intent, obviously. The model does not wake up and decide to sabotage a transmission grid. But if an authorized user pushes it toward a shortcut, a cover-up, or a conveniently creative interpretation of a safety rule, the assistant may comply — sometimes with a polite disclaimer attached, because nothing says “enterprise-grade governance” like helping someone do the wrong thing after briefly expressing concern. ...

In the high-stakes world of smart grids, digital substations have become both operational nerve centers and prime targets for cyberattacks. IEC61850-based communication, particularly GOOSE multicast messages, enables faster coordination but also introduces new vulnerabilities — especially for unmanned substations that rely heavily on remote access. Traditional anomaly detection systems (ADSs), while effective in standard IT contexts, falter here: they require continual retraining for each new threat and often struggle with scarce, imbalanced datasets. ...
